The FDA warns healthcare providers of a Class I recall of some of Maquet Cardiovascular's malfunctioning battery units. A Class I recall, reserved for serious patient harm, was issued over battery units produced by Getinge (PINK:GETI B) subsidiary Maquet Cardiovascular. The batteries, which power ventilators used during intra-hospital transport of patients from neonates to older adults, have a shorter lifetime than expected, meaning the ventilators may shut down prematurely.
